Correlations in emitters coupled to plasmonic waveguides
Cristian E. Susa, John Henry Reina, Luis Lorenzo Sánchez-Soto · 2016
Abstract. We report on quantum, classical, and total correlations in a set of distant quantum emitters coupled via their interaction with the plasmon modes of a one-dimensional waveguide driven by an external laser field. The coupling of the emitters with the plasmonic modes and its influence on the collective decay rate suggest that entanglement does not play a significant role in the qubit dynamics. Rather, discord is the quantity that matters and should be harnessed as a resource. PACS numbers: 03.65.Ud, 03.67.Lx, 42.79.Gn 1.
